The National International Health Regulations (IHR) Focal Point of Uruguay announced last week that the country has seen a sustained increase in the number of suspected cases – 570 – and confirmed cases – 17 – of dengue fever.
All confirmed cases were positive for dengue virus by reverse transcription polymerase chain reaction (RT-PCR). The serotype circulating is DEN 1.
Health authorities in Uruguay have implemented measures for strengthening integrated vector control, along with updating clinical management guidelines and emergency risk communications. An international team of experts has been deployed to support response operations.
The World Health Organization (WHO) has indicated that proximity to mosquito breeding sites is a significant risk factor for the spread of dengue fever. Prevention and control relies on reducing the number of breeding sites and reducing human to mosquito contact. Decreasing mosquito populations can be achieved by using insect screens, long clothing and repellants and by using water filtration and treatments that reduce larvae populations.
It is also recommended for those who sleep during the daytime use mosquito nets treated with insecticide.
For those traveling to high-risk areas, the WHO recommends the use of repellants, long-sleeved shirts and pants, and the use of screens to cover all doors and windows.
